Onsen Geisha Since Birth

Hinako, a geisha, comes from a family of three generations of geisha. She started her career as a geisha in earnest after breaking up with her childhood friend and boyfriend from an old family. She and her fellow geisha friends, Koyomi and Mitsuba, get along well, entertaining customers whenever they feel like it, but Mitsuba is pregnant with the child of a man who comes once a month on business.
